A review on aluminum matrix composites' characteristics and applications for automotive sector.

In recent years, the auto industry has experienced significant advancements, making research and development (R&D) of vehicle materials increasingly vital. Aluminum matrix composites (AMCs), known for their lightweight, high strength, and excellent corrosion resistance, have demonstrated substantial potential in vehicle aesthetics, interior trim, power systems, and components manufacturing. Currently, aluminum-metal composites (such as Cu and Mg) and aluminum-nonmetal composites (including Si, C, and plastics) are the primary types of AMCs used in automobiles. A thorough investigation into their preparation, process mechanisms, and performance optimization is essential for the broader application of AMCs in new vehicle models. This review summarizes and analyzes the preparation methods, wear mechanism, performance enhancement strategies, strengthening mechanism, and economic impact of AMCs, discussing key influential factors to foster the development of new AMCs. Additionally, by examining the role of aluminum compound packing films in the pouch batteries of Electric Vehicles, also explores the future potential of AMCs within the new energy power sector.
